Mica gasket material is exceptional in it resistance to high heat. At temperatures over 900 F the ideal sealing material Grafoil or flexible graphite cannot be used. Flexible graphite or Grafoil will coke at those elevated temperatures when oxygen is present, where mica gasket material will not (900 - 1850 F).
We are now stocking FMI Micatherm which is a mica bound with stainless steel for strength.
Mica gasket material is an excellent alternative in these high temperature (to 1800 F) applications. Some of the basics on Mica are shown below. As a gasket material Mica can be very effective in sealing those high temp critical applications with out failing due to the presence of oxygen.
Mica is a mineral, which offers a wide range of exceptional properties.
You may find that some of the properties of mica could improve the different products in your range.
Mica which comes in the form of flaks is completely harmless and presents very high thermal and mechanical performances, allowing it to successfully replace asbestos gasket material in many applications.
American Seal & Packing offers a wide range of gasket materials, each corresponding to specific requirements and designed for a well-defined application. American Seal & Packing can assist you in determining which mica gasket material (or other material) corresponds best to your application.
